16 | * | |
17 | * - support for UAC2 effect units | |
18 | * - support for graphical equalizers | |
19 | * - RANGE and MEM set commands (UAC2) | |
20 | * - RANGE and MEM interrupt dispatchers (UAC2) | |
21 | * - audio channel clustering (UAC2) | |
22 | * - audio sample rate converter units (UAC2) | |
23 | * - proper handling of clock multipliers (UAC2) | |
24 | * - dispatch clock change notifications (UAC2) | |
25 | * - stop PCM streams which use a clock that became invalid | |
26 | * - stop PCM streams which use a clock selector that has changed | |
27 | * - parse available sample rates again when clock sources changed | |
